Problems solved by technology

Chemical decolorizers will destroy the beneficial components of wood wax, increase wood wax oxides that are not beneficial to the human body, and easily lead to chemical residues
In addition, these methods require the use of complex equipment and confined spaces, and leakage can cause serious social hazards
[0004] In addition, the wood wax produced by the current process has many disadvantages such as softness, dull surface, insufficient toughness, and high peroxide content, while the deep-processing products of wood wax have high cost, small scale, and large environmental pollution, which seriously restricts the utilization of wood wax
[0005] Chinese patent 102167995 discloses a method for decolorizing and modifying lacquer wood wax, mainly through ultraviolet irradiation. This method requires high equipment, and improper use of ultraviolet rays will cause serious harm to workers
In addition, this method needs to add ultraviolet absorber benzophenone, which requires high cost, and benzophenone has certain toxicity, and benzophenone residues are likely to exist in the refined wood wax
Chinese patent 101348750 discloses a decolorization method of Chinese wood wax, and its process method cannot reduce the peroxide content and insufficient toughness of the obtained refined wood wax
In addition, the temperature requirement in the process is high, the energy consumption is large, and the cost of the whole process is high, which is not conducive to large-scale industrial production

Embodiment 1

[0031] Put 10 kg of unprocessed crude Chinese wood wax into a steam heating pot, melt it at 60-70℃, use a plunger pump to send it into the filter press and filter through a 200-mesh coarse-pore filter membrane, and add relative wood wax volume to the resulting filtrate Stir a 100% 0.1% oxalic acid solution preheated to 90°C at a stirring speed of 500 r / min and stir for 20 min. Cool the obtained wood wax to room temperature, and then wash it twice with water. After drying, the washed wood wax is added back to the steam heating pot again, and 2% of the weight of the wood wax is added to the crude activated carbon of 10 mesh, and the mixture is stirred for 1.5 h at a stirring speed of 500 r / min. After the stirring, the wood wax with Gardner's color scale of about 3-4 is obtained. The above mixture is sent to the filter press with a plunger pump and filtered through a fine-pore filter membrane. The obtained filtrate is again added with relative wood 30 mesh refined activated carbon...

Embodiment 2

[0041] 20 kg of unprocessed crude Chinese wood wax is put into a steam heating pot, melted at 60-70℃, and then sent to the filter press with a plunger pump and filtered through a 300-mesh coarse-pore filter membrane. The relative volume of wood wax is added to the filtrate obtained 150% pre-heated to 90 ℃ containing 0.5% oxalic acid and 0.1% sodium tetraborate decahydrate solution was stirred, stirring speed 500 r / min, stirring for 20 minutes, the obtained wood wax was cooled to room temperature, and then washed with water 5 Times. After drying, add the washed wood wax back to the steam heating pot again, and then add 8% of the weight of the wood wax to 20 mesh crude activated carbon and 20% of the weight of the wood wax to acid clay, and stir for 1 h, stirring speed 500 r / min. After the stirring, the wood wax with Gardner color scale of 3 is obtained. The above mixture is pumped into the filter press with a plunger and filtered through a fine-pore filter membrane. The obtaine...

Embodiment 3

[0051] Put 10 kg of unprocessed crude Chinese wood wax into a steam heating pot, melt it at 60-70℃, use a plunger pump into the filter press to filter through a 200-mesh coarse-pore filter membrane, and add relative wood wax volume to the resulting filtrate 120% pre-heated to 90℃ containing 0.4% oxalic acid, 0.5% sodium tetraborate decahydrate and 15% soybean oil solution was stirred at a stirring speed of 600 r / min, stirring for 20 min, and the obtained wood wax was cooled to room temperature , And then wash 4 times with water. After drying, add the washed wood wax back to the steam heating pot again, and then add 4% 15 mesh crude activated carbon relative to the weight of the wood wax and 10% acid clay relative to the weight of the wood wax, and stir for 1 h, stirring speed 500 r / min. After the stirring, the wood wax with Gardner's color scale of 3 is obtained. The above mixture is pumped into the filter press with a plunger and filtered through a fine-pore filter membrane. ...

Abstract

The invention provides a refining process for vegetable wax. Coarse vegetable wax is refined by step impurity removal, discoloration and deodorization. The process has simple requirements on equipment, and is extensive in raw material sources, low in cost and suitable for industrial application, and negative influence on producers and the environment is eliminated.

Description

Technical field [0001] The present invention relates to a process method for wood wax treatment, and more specifically, to a process method for refining wood wax. The wood wax obtained by the method can be used in food, medical products, cosmetics and other aspects. Background technique [0002] Wood wax is mainly a fatty substance extracted from the peels of plants of the same genus as Japanese wood wax, such as sumac. Traditionally, wood wax is extracted by boiling or pressing. The resulting product contains many impurities, resulting in yellow or yellow-brown wood wax. The mixing of metal ions in the process will also cause the wood wax to deepen its color, which will seriously affect the appearance quality and use performance, and is not conducive to subsequent direct use. [0003] At present, there are some reports on the treatment of crude wood wax, mainly through chemical decolorization. Chemical decolorants will destroy the beneficial components of wood wax, increase wood ...
